Title: Safety apparatus in direct pressing type mold locking apparatus
Inventor: UMEMOTO HIROSHI
IPC: B29C45/77
Filed: 1987-01-19
Abstract: PURPOSE:To prevent a mold from breaking by stopping driving of an induction motor when a timer makes a time-up before a movable platen reaches a position of a set mold locking force or when an output force is put from a distinguishing means. CONSTITUTION:Opening and closing of a mold are carried out with a fast opening and closing speed by means of a serbomotor. The position of a movable platen is detected by means of a position detector being set on the serbomotor B. When reached to a mold touch position, an induction motor C is driven and a mold locking action is carried out with a large force by means of the induction motor. On the other hand, when reached to the mold touch position, a timer means E starts to check time and if the timer means E makes a time-up before reaching the position setting a mold locking force, a controlling circuit D stops the driving of the induction motor. When reached the position setting a mold locking force and although a sign for stopping the driving of the induction motor is output, if the position of the movable platen A continues to move over the allowable position due to a trouble of a brake and so on, an urgent stop sign is output, an electric power switch is turned off and the driving of the induction motor is stopped. The breakage of the mold is thereby prevented.

Title: Manufacture of semiconductor laser
Inventor: MURAI HITOSHI
IPC: H01S5/00
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To form an SiO2 mask by self alignment for etching the active layer of a semiconductor laser, and make the shape of its mesa independent of the orientation of the crystalline plane of its substrate and the direction of its mesa, by batch-forming its mesa stripe and a second SiO2 mask through dry etching. SOLUTION: When reactive ion etching is performed on a second SiO2 film 6 grown thinner than a first SiO2 film 5, the film 6 is etched over its growing surface to reach a p-InP clad layer 3. The first SiO2 film 5 is left and the second SiO2 films 6 deposited on the side surfaces of a contact layer 4 are not etched either. Then, only an InGaAsP active layer 2 is etched. Thereby, the pattern of the second SiO2 film 6 can be formed by self alignment. Also, since a dry etching method is used, any change of the shape of a mesa caused by the variations of the orientation of the crystalline plane of a substrate and the direction of the mesa is not generated and a stable process is obtained.

Title: Bipolar type semiconductor device
Inventor: OZAWA KUMIKO
IPC: H01L29/73
Filed: 1993-01-22
Abstract: PURPOSE:To improve the breakdown strength between a base and a collector and the resistance inside the collector without lessening the elongation of a depletion layer generated at the end of the p-region formed at the end of the base, by installing a low-concentration area at the middle part of a buried region. CONSTITUTION:The first buried region 20, which contains n-type impurities, for example, antimony, is made in the vicinity of the surface of a p-type semiconductor substrate 22, which contains boron as impurities. This process selectively installs the buried regions, making use of public photolithography or ion implantation process, and forms the n-type second buried region 21 lower in concentration between them. Subsequently, an epitaxial growth layer 23, which operates as the collector of an NPN transistor and contains, for example, P, is accumulated. Hereby, the breakdown strength between the collector and the base and the collector resistance can be improved.

Abstract: PURPOSE:To obtain an electrode which has a large contact strength and from which a ball hardly separates by laminating in order from the n-type layer side a first multilayer thin film which is formed by laminating Ti-Al alloys or depositing Ti and Al and a second thin film which is constituted of a metal which has a higher melting point than Al. CONSTITUTION:An electrode formed on the surface of an n-type layer 2 is formed by laminating in order from the n-type layer 2 side a first multilayer thin film which is formed by laminating Ti-Al alloys or depositing Ti and Al and a second thin film which is constituted of a metal which has a higher melting point than Al. The metals which have a higher melting point than Al and which can be used for the second thin film include Au, Ti, Ni, Pt, W, Mo, Cr and Cu. Among them, Au, Ti, and Ni are preferable. Due to this structure, the electrode can have a good ohmic contact with the n-type layer and the electrode and a ball hardly separate from each other and therefore the electrode becomes such a one that has a large contact strength.

IPC: H02P7/29
Filed: 1994-01-28
Abstract: PURPOSE:To turn on a MOS transistor securely and realize the normal and stable motor driving control by a method wherein a charge pump circuit is provided. CONSTITUTION:A driving voltage DV which normally exceeds the threshold voltages of MOS transistors F11 and F12 is generated by a charge pump circuit 14 and is/is not applied between the gates and sources of the MOS transistors F11 and F12 which are connected to the positive power supply +Vcc side of a bridge circuit 11 through first and second switching circuits 12 and 13. Therefore, when the MOS transistors F11 and F12 which are connected to the positive power supply +Vcc side are to be in ON-states for a long time, the trouble that the gate-source voltages are lower than the threshold voltages and the MOS transistors F11 and F12 are not turned on and the normal and stable motor driving control becomes impossible can be avoided.

Title: Delay circuit for semiconductor integrated circuit
Inventor: FURUYA KIYOHIRO
IPC: G11C11/4074
Filed: 1989-01-17
Abstract: PURPOSE:To make a delay time constant independently of fluctuation of a power voltage by supplying a output of a constant voltage generating circuit to an inverter. CONSTITUTION:The above circuit consists of CMOS logic circuits 1, 3 fed with an external power supply Vcc, a constant voltage generating circuit 4 generating an internal power supply (Int.Vcc) and a delay circuit 2 being a CMOS circuit receiving an internal power supply and a delay time from a node N2 to a node N5 is similar to a delay time of the delay circuit 2 because the delay time from the node N5 to the node N6 is sufficiently small. The inverter located between the nodes N1 and N2 acts like converting a signal at the node N1 whose level is Vcc into a signal whose level is Int.Vcc. The Int.Vcc is supplied to the inverter located between the nodes N2 and N5, thus the delay time between the node N2 and N5 is constant independently of the external power supply Vcc. Thus, the delay time of the delay circuit 2 is made constant independently of the external power supply Vcc.

Title: Method for inserting bush in carriage of printer under pressure
Inventor: ONO KEIKICHI
IPC: B41J19/20
Filed: 1991-01-29
Abstract: PURPOSE:To prevent the excessive contraction of an inner diameter or the shift of a center axis by inserting a pair of bushes in the through-hole of a carriage under pressure in such a state that an assembling shaft is inserted in the bushes. CONSTITUTION:Bushes 5, 5 are arranged in opposed relation to both mouth parts of a through-hole 2 and an assembling shaft 41 is pushed out by an auxiliary cylinder 40 to be inserted in the bushes 5, 5. Next, pistons 21, 31 are pushed out of two pressure inserting cylinders 20, 30 to insert the bushes 5, 5 in the through-hole 2 of a carriage 1 under pressure. Thereafter, the assembling shaft 41 is retracted toward the auxiliary cylinder 40 and the pistons 21, 31 are also retracted toward the cylinders. Since the bushes are assembled with high accuracy in such a state that the inner diameter dimension and center axis of the bushes after pressure insertion are held to a desired dimensional shape, a product of high quality can be stably manufactured and, since pressure insertion inferiority is eliminated, additional processing becomes unnecessary and marked cost-down effect can be obtained.

Title: Image information combining method
Inventor: TAUBMAN DAVID S
IPC: H04N5/44
Filed: 1999-01-18
Abstract: PROBLEM TO BE SOLVED: To reduce not only luminance and color aliasing defects regarding a reference field, but also noise while increasing resolution by selecting one field as a reference one, discriminating the remaining fields as auxiliary fields, and making use of information from the auxiliary fields. SOLUTION: When the numbers of rows and the numbers of columns of digitized video fields are represented as HF and WF, a multi-field processing system interpolates the reference field directionally to resolution HI=4HF and WI=WF and then merges directionally interpolated, motion-corrected, and properly weighted auxiliary fields adaptively with the reference field to reinforce vertical directional information contents. This adaptive merging process is useful to remove aliasing and reduce noise.
